2. Noise Source Distribution of Coaxial Subsonic Jet-Short-Cowl Nozzle
ABSTRACT: The noise source distribution of a short-cowl coaxial jet operating at different velocity ratios is described in this work. This was motivated by an ongoing research about noise prediction of coaxial jets through Acoustic Analogy with purposes of industrial engine application. This research has been carried out between Universidade Federal de Uberl

3. Vibroacustografia na avaliação tridimensional de artroplastia total de quadril / Vibro-acoustography in the tridimensional evaluation of total hip arthroplasty
Vibro-acoustography (VA) is a high lateral resolution (<0.7 mm), speckle-free, non- ionizing and non-invasive image based on the nonlinear combination phenomenon of ultrasound waves (MHz) that generates a narrow focus region of low frequency (kHz). In this work, we propose a VA-based tridimensional evaluation of the exposed area of implants, after total hip

4. IN SEARCH OF A NEW PORTUGUESE CINEMA / EM BUSCA DE UM NOVO CINEMA PORTUGUÊS
In search of a new Portuguese cinema talks about the genesis of this movement that became known as this is a huge transformation in the way of seeing and making movies in Portugal. As shown clearly, many debates about the social function of art grew out of discussions on the impasse reached between the art of modernist bias, and the other features neorealist

5. Desenvolvimento de um algoritmo híbrido de fotometria estelar a partir de imagens do espaço. / Development of a hybrid algorithm for time-resolved stellar photometry from space images.
CoRoT (Convection, Rotation and planetary Transits) é uma missão espacial liderada pela Agência Espacial Francesa (CNES) em associação com diversos parceiros internacionais, entre eles o Brasil. Seus objetivos principais são o estudo da sismologia estelar e a procura por planetas extra-solares (exoplanetas). Ambos os programas científicos baseiam-se e

6. Simulation of optical and physiological phenomena of the human vision / Simulação de fenômenos óticos e fisiológicos do sistema de visão humana
The increase in performance of the modern computers has driven scientific work in the areas of computer simulation. Many authors use in their research commercial tools that use embedding algorithms, which sources are not provided, and it makes harder and sometimes impossible, the development of novel theories or experiments. This work explores this gap left

7. A necessidade da efetivação das regiões metropolitanas
The expansion of the city is based by the quantitative expansion of the technological potential whose objective is to extend the physical forces of the man in its necessities to live, to circulate and to work; e the way for which it expands - of dispersed form or intently - it is in the dependence of the form as the some technological elements are spread. Su

8. Estimação da resolução espacial da câmera CCD dos satélites CBERS 1 e 2 / Spatial resolution estimation of CBERS CCD camera
The first China-Brazil Earth Resources Satellite (CBERS-1) was launched in 1999 and was substituted on 2003 by CBERS-2. CBERS- 1 and CBERS-2 have the same specifications and carry three sensors: a Wide Field Imager (WFI), a High Resolution CCD Camera (CCD) and an Infrared Multispectral Scanner (IRMSS). Due to the limitations of the sensor components (diffrac

12. Visualization study and quantitative velocity measurements in turbulent taylor-couette flow by phantomm flow tagging: a description of the transition to turbulence
A visualization study and Quantitative velocity measurements have been performed in Taylor-Couette flow with a medium-gap (ç= 0.356), over a large range of Taylor numbers (2.1x10(4) < Ta < 1.1x10(11)), with the outer cylinder fixed and the inner cylinder rotating about its axis. Quantitative velocity measurements were carried out using the PHANTOMM flow tag
